Well they keep saying the Magic that Frigga taught Loki IS a science, but they don't over explain it anywhere like they did with the force, and I'm happy with that.
Silver Surfer and FF use Cosmic Energies while Asgardians use what has been called "Odin Force and Thor Force" in the comics. It's energy more than likely unseen by humans. I like to called it Rune Force because it IS sentinent and only one All-Father at a time may use the power.
